Default BBS CH center cap dimensions?

Can anyone tell me what size the BBS center caps are for genuine CHs for the B5 S4? I know the face of the cap is 70mm, but what is the back size? Is it 56mm or 64mm?

Default Somewhere on the Intarweb, there is a chart that lists the back sizes of all the caps for the

various BBS wheels. I've seen it before, but I'm not sure how to find it...

Default I've seen that chart

but for the 18x9.5 CHs with a 70mm face, it lists 2 back sizes; 56mm and 64mm, I don't know which one of those two to order.

You can either pull one of the caps off and check, or call BBS, but you'll need to have your wheel PN handy. It's stamped on the wheel somewhere. CHXXX where XXX is a 3 digit pn.

We carry all the replacement center caps you need!

Bumping this up. Did you ever find the correct center caps for the CH's?

I also have a question about CH centercaps.

What are the specs for the Audi BBS CH centercaps? I was told that the factory Audi CH wheels (CH028), 18x8 et 43, are different than "regular" aftermarket CH's.

Anybody know for sure?

Yup, the appropriate sizes were 70mm for the face, and 64mm for the back

So just to reiterate, the 70mm/64mm type C caps from PureMS [link] will fit the OEM BBS CH028 18x8 et43 wheels without issue? I am asking because i could not get a 64mm measurement from any point on the back of the stock caps.
